PHPExcel setAutoSize for merged cells

PHPphpexcel

Code without merge

$objPHPExcel = new PHPExcel();
$sheet = $objPHPExcel->getActiveSheet();

$sheet->setCellValueByColumnAndRow(0, 1, 
        "test test test test test test test test");
$sheet->getColumnDimension('A')->setAutoSize(true);

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save("test.xlsx");

Code with merge

$objPHPExcel = new PHPExcel();
$sheet = $objPHPExcel->getActiveSheet();

$sheet->setCellValueByColumnAndRow(0, 1, 
        "test test test test test test test test");
//this breaks the width calculation
$sheet->mergeCells('A1:B1');
$sheet->getColumnDimension('A')->setAutoSize(true);

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save("test.xlsx");

As far as I understand, there is no standard way to set auto size for merged cells. Is there any workaround for this?

Best Answer

You could calculate the column widths before merging the cells using ->calculateColumnWidths(), and then ->setAutoSize(false) to make sure that they are not calculated again. The code could look something like this:

// Set the data in the cells
$objPHPExcel->getActiveSheet()->fromArray($sheet, null, 'A1');

// Calculate the column widths
foreach(range('A', 'E') as $columnID) {
    $objPHPExcel->getActiveSheet()->getColumnDimension($columnID)->setAutoSize(true);
}
$objPHPExcel->getActiveSheet()->calculateColumnWidths();

// Set setAutoSize(false) so that the widths are not recalculated
foreach(range('A', 'E') as $columnID) {
    $objPHPExcel->getActiveSheet()->getColumnDimension($columnID)->setAutoSize(false);
}

// Merge cells
$objPHPExcel->getActiveSheet()->mergeCells("A1:A5");

You might be exceeding the 65,000 limit, what do you set the $rowscounter initial value at? 1 or 0 (zero)? The reason I ask it that the array results starts at index 0 (zero), you're adding the row and then incrementing the counter after the add. So if you start the counter at 0 (zero) than you might have more rows that what you have counted. Also you are missing a row in the else statement, you loop through a value but don't add it to the sheet

try this

$rowscounter = 1;

foreach($result as $value)
{
    $val = array_values($value);

    if($rowscounter < 65000)
    {
        $objPHPExcel->addRow($val,$rowscounter);
    }
    else
    {
        $active_sheet++;
        $objPHPExcel->createSheet();
        $objPHPExcel->setActiveSheetIndex($active_sheet);
        $rowscounter = 1;

        // add missing row
        $objPHPExcel->addRow($val,$rowscounter);
    }
    $rowscounter++;
}
// deliver header   
header("Content-Type: $mtype; charset=" . $objPHPExcel->sEncoding);
header("Content-Type:application/octet-stream");
header("Content-Disposition: inline; filename=\"" . $filename . ".$ext\"");

// Save it as an excel 2003 file
$objWriter = IOFactory::createWriter($objPHPExcel,$objPHPExcel->sFileFormat);
//echo "Peak memory usage: " . (memory_get_peak_usage(true) / 1024 / 1024) . " MB";exit;
$objWriter->save('php://output');

a simple example of what I'm trying to explain, if $i is set to 0 (zero) the else condition is not met. So you will have an extra row in your results. If $i is set to 1 the else condition is met

$count = array(1,2,3,4,5,6,7,8,9,10);
$i=1; // set this to 0 (zero) and test, set to 1 and test

foreach($count as $cnt) {
    if($i < 10) {
        echo "If condition - Count value: ".$cnt." i value:".$i."<br />";
    } else {
        echo "Else condition - Count value: ".$cnt." i value:".$i."<br />";
    }
    $i++;
}
